A geographic information system uses computers and software to explain the fundamental principles of geography --that location is important in people’s lives.
"Chances are that GIS technology has already touched your life. If you flipped on a light switch today, chances are that GIS was used to help make sure the electricity was there to light up the room. When you drove down a highway, chances are that GIS was used to keep track of the signs and streets along the way. If you received a delivery, chances are that GIS helped the driver find the way to your house. If you bought fresh vegetables, chances are that GIS helped manage the land and calculate the fertilizer needed for the crop. If you looked at a map on the Internet, chances are that GIS had a hand in that too.
A geographic information system (GIS) uses computers and software to organize, develop, and communicate geographic knowledge. In simple terms, GIS takes the numbers and words from the rows and columns in databases and spreadsheets and puts them on a map". (ESRI Mapping OurWorld)

Much information is tied to a location and a map shows patterns in the data we might not otherwise see. GIS can layer many types of maps to help people make decisons about where to build roads, business, and homes. Putting data on a map helps you asks questions like “where?”, “why?” and “how?” with locational information in mind. With geographic knowledge you can make better decisions.
